Effect of Grazing Stubble Height and Season on Establishment, Persistence, and Quality of Creeping Bluestem [PDF]

open access: yesJournal of Range Management, 1986
Creeping bluestem (Schizachyrium stoloniferum) was grazed every 6O-days to 15 or 30-cm stubble heights during the following 4 periods (seasons): (1) June, Aug., Oct. (JAO); (2) Oct., Dec., Feb. (ODF); (3) Feb., Apr., June (FAJ); (4) year-long (YL). Average diameter (37 cm) of piants grnzed in JAO and YL to lS-cm stubble was less (PC 0.05) than piants ...
